These systems are Roça sem Fogo, Jardim de Reciclagem, Parcagem, and semimechanized. Roça sem Fogo consists in preparing the land by slashing a secondary forest fragment and chopping the plant materials on the soil. Jardim de Reciclagem is a legume tree–cassava intercropping in which tree branches are pruned and chopped on the soil. Parcagem is a traditional practice of fertilizing the soil with excreta deposited directly by cattle. In turn, semimechanized is a system based on mechanized tillage. Also, the chapter describes manipueira, a liquid organic waste from cassava flour production that currently is discarded in soils and surface waters without any criteria, improves the performance of Roça sem Fogo by increasing the root yield of the crop. In conclusion, the combination of a fire-free cultivation system and manipueira has the potential to be more sustainable by increasing the cassava root yield while minimizing the environmental impact resulting from the use of fire in agriculture and the inadequate discard of organic wastes. However, experimental studies are needed to define the most efficient and safer use of manipueira in soils.  aMandioca  aManihot Esculenta  aResíduo Orgânico  aSistema de Cultivo  aAgricultura de corte e queima  aJardim de Reciclagem  aParcagem  aRoça sem fogo  aSemimecanizado1 aMODESTO JUNIOR, M. de S.1 aSILVA, A.
